Emails, interview, not a lot of technical questions

Interview process started with a phone screen with a technical manager (above ~25 people). After a few questions about my background, he gave me information about the department and some hard drive overview information. One week later, I was flown to San Jose for my on-site interview, which consisted of seven 1:1 interviews with engineers and technical managers followed by an informational interview with HR to discuss benefits. Interviewers seemed very interested in my background and technical/design experiences. Some asked me technical questions (mostly textbook-based about strength, stiffness, material properties, frequency analysis), some asked about my background and projects, some asked me some "puzzlers," and all asked what I was interested in doing if I join the group (CAD, testing/qualification, or analysis).
